	Note 1—Organization
	Organization
	The Partnership is a fee-based, growth-oriented Delaware limited partnership formed by Lightfoot in 2007 to own, operate, develop and acquire a diversified portfolio of complementary energy logistics assets. The Partnership is principally engaged in the terminalling, storage, throughput and transloading of crude oil and petroleum products. The Partnership is focused on growing its business through the optimization, organic development and acquisition of terminalling, storage, rail, pipeline and other energy logistics assets that generate stable cash flows.

References to “Center Oil” refer to GP&W, Inc., d.b.a. Center Oil, and affiliates, including Center Terminal Company-Cleveland, which contributed its limited partner interests in Arc Terminals to the Partnership upon the consummation of the IPO. References to “Gulf LNG Holdings” refer to Gulf LNG Holdings Group, LLC and its subsidiaries, which own a liquefied natural gas regasification and storage facility in Pascagoula, MS, which is referred to herein as the “LNG Facility.” The Partnership used a portion of the proceeds from the IPO to acquire a 10.3% limited liability company interest in Gulf LNG Holdings, which is referred to herein as the “LNG Interest.”
	Initial Public Offering
	In November 2013, the Partnership completed its IPO by selling 6,786,869 common units (which includes 786,869 common units issued pursuant to the exercise of the underwriters’ over-allotment option) representing limited partner interests in us at a price to the public $19.00 per common unit. In connection with the IPO, the Partnership amended and restated the Terminal Credit Facility (as defined below, see “Note 7—Debt”).
	The $120.2 million of net proceeds from the IPO (including the underwriters’ option to purchase additional common units and after deducting the underwriting discount and structuring fee) were used to: (i) fund the purchase of the LNG Interest from an affiliate of GE Energy Financial Services (“GE EFS”) for approximately $72.7 million; (ii) make a cash distribution to GCAC as partial consideration for the contribution of its preferred units in Arc Terminals LP to the Partnership of approximately $29.8 million; (iii) repay intercompany payables owed to the Sponsor of approximately $6.6 million; and (iv) reduce amounts outstanding under the Partnership’s Credit Facility by $6.0 million. The remaining funds were used for general Partnership purposes, including the payment of transaction expenses related to the IPO and the Credit Facility.

Summary of Significant Accounting Policies	'
	Note 2—Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and under the rules and regulations of the Securities and Exchange Commission (“SEC”). The accompanying consolidated financial statements include the accounts of the Partnership and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	The Partnership has disclosed consolidated figures of the Partnership as if the Partnership had operated since the inception of Arc Terminals. The contribution of Arc Terminals to Arc Logistics in connection with the IPO was not considered a business combination accounted for under the purchase method as it was a transfer of assets under common control and, accordingly, balances have been transferred at their historical cost. The combined financial statements for the periods prior to the contribution on November 12, 2013 have been prepared using Arc Terminals’ historical basis in the assets and liabilities, and include all revenues, costs, assets and liabilities attributed to Arc Terminals.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The most significant estimates relate to the valuation of acquired businesses, goodwill and intangible assets and the useful lives of intangible assets and property, plant and equipment. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	The Partnership includes demand deposits with banks and all highly liquid investments with original maturities of three months or less in cash and cash equivalents. These balances are valued at cost, which approximates fair value.
	Trade Accounts Receivable
	Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Partnership reserves for specific trade accounts receivable when it is probable that all or a part of an outstanding balance will not be collected. The Partnership regularly reviews collectability and establishes or adjusts the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. There were no reserves for uncollectible amounts as of December 31, 2013 and 2012. During the year ended December 31, 2013, the Partnership wrote off less than $0.1 million of uncollectible receivables. No other amounts have been deemed uncollectible in the periods presented in the consolidated statements of operations.
	Inventories
	Inventories consist of additives which are sold to customers and mixed with the various customer-owned liquid products stored in the Partnership’s terminals. Inventories are stated at the lower of cost or estimated net realizable value. Inventory costs are determined using the first-in, first-out method.
	Other Current Assets
	Other current assets consist primarily of prepaid expenses and deposits.
	Property, Plant and Equipment
	Property, plant and equipment is recorded at cost, less accumulated depreciation. The Partnership owns a 50% undivided interest in the property, plant and equipment at two terminal locations. At the time of acquisition, these assets were recorded at 50% of the aggregate fair value of the related property, plant and equipment. Expenditures for routine maintenance and repairs are charged to expense as incurred. Major improvements or expenditures that extend the useful life or productive capacity of assets are capitalized. Depreciation is recorded over the estimated useful lives of the applicable assets, using the straight-line method. The estimated useful lives are as follows:
	Building and site improvements		5 - 40 years
	Tanks and trim		2 - 40 years
	Machinery and equipment		2 - 25 years
	Office furniture and equipment		3 - 10 years
	Capitalized costs incurred by the Partnership during the year for major improvements and capital projects that are not completed as of year-end are recorded as construction in progress. Construction in progress is not depreciated until the related assets or improvements are ready for intended use. Additionally, the Partnership capitalizes interest costs as a part of the historical cost of constructing certain assets and includes such interest in the property, plant and equipment line on the balance sheet. Capitalized interest for the years ended December 31, 2013 and 2012 was $0.4 million and $0.1 million, respectively.
	Intangible Assets
	Intangible assets primarily consist of customer relationships, acquired contracts and a covenant not to compete which are amortized on a straight-line basis over the expected life of each intangible asset.
	Impairment of Long-Lived Assets
	Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated.
	During the year ended December 31, 2013, events and circumstances indicated that approximately $4.7 million of assets of one of the Partnership’s terminals might be impaired. However, the Partnership’s estimate of undiscounted cash flows indicated that such carrying amounts were expected to be recovered. Nonetheless it is possible that the estimate of undiscounted cash flows may change in the near term resulting in the need to write down the carrying value of those assets.
	No impairment charges were recorded through December 31, 2013 and 2012.
	Goodwill
	Goodwill represents the excess of consideration paid over the fair value of net assets acquired in a business combination. Goodwill is not amortized but instead is assessed for impairment at least annually or when facts and circumstances warrant. Goodwill impairment is determined using a two-step process. The first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. The Partnership determines the fair value of its single reporting unit by blending two valuation approaches: the income approach and a market value approach. The Partnership determined at December 31, 2013, there were no impairment charges and no event indicating an impairment has occurred.
	No impairments were recorded against goodwill through December 31, 2013 and 2012.

	Goodwill acquired		8,432		—
	Impairment		—		—
	Ending Balance	$	15,162	$	6,730
	Other Assets
	Other assets consist primarily of debt issuance costs related to the Credit Facility amendment entered into in November 2013 (see “Note 7—Debt”). Debt issuance costs are capitalized and amortized over the term of the related debt using straight line amortization, which approximates the effective interest rate method. As of December 31, 2013, these costs were approximately $1.7 million. Fluctuations during the year ended December 31, 2013 included write offs of approximately $3.5 million, representing the unamortized debt issuance cost prior to the refinancing of the debt and approximately $2.9 million in deferred costs associated with the IPO that were offset against the proceeds of the IPO.
	Investment in Unconsolidated Affiliate
	In connection with the IPO, the Partnership purchased the LNG Interest from an affiliate of GE EFS for approximately $72.7 million. The Partnership accounts for the LNG Interest using the equity method of accounting.
	Revenue Recognition
	Revenues from leased tank storage and delivery services are recognized as the services are performed. Revenues also include the sale of excess products and additives which are mixed with customer-owned liquid products. Revenues for the sale of excess products and additives are recognized when title and risk of loss passes to the customer.
	Income Taxes
	Taxable income or loss of the Partnership generally is required to be reported on the income tax returns of the limited partners in accordance with the terms of the partnership agreement. Accordingly, no provision has been made in the accompanying consolidated financial statements for the limited partners’ federal income taxes. There are certain entity level state income taxes that are incurred at the Partnership level and have been recorded during the years ended December 31, 2013, 2012 and 2011.
	Tax returns for the years ended December 31, 2013, 2012, 2011, 2010 and 2009 are open to IRS and state audits. The Partnership is not aware of any uncertain tax positions as of December 31, 2013 and 2012.
	Fair Value of Financial Instruments
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Fair value measurements are derived using inputs and assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. GAAP establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This three-tier hierarchy classifies fair value amounts recognized or disclosed in the financial statements based on the observability of inputs used to estimate such fair values. The classification within the hierarchy of a financial asset or liability is determined based on the lowest level input that is significant to the fair value measurement. The hierarchy considers fair value amounts based on observable inputs (Level 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). At each balance sheet reporting date, the Partnership categorizes its financial assets and liabilities using this hierarchy.
	The amounts reported in the balance sheet for cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value because of the short-term maturities of these instruments (Level 1). The carrying amount of the Terminal Credit Facility as well as the Partnership’s Credit Facility approximated fair value due to its short-term nature and market rate of interest (Level 2).
	The Partnership believes that its valuation methods are appropriate and consistent with the values that would be determined by other market participants. However, the use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.
	Limited Partners’ Net Income Per Unit
	The Partnership uses the two-class method in the computation of earnings per unit since there is more than one participating class of securities. Basic earnings per common and subordinated unit are determined by dividing net income allocated to the common units and subordinated units, respectively, after deducting the amount allocated to the preferred unitholders, by the weighted average number of outstanding common and subordinated units, respectively, during the period. The overall computation, presentation and disclosure of the Partnership’s limited partners’ net income per unit are made in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260 “Earnings per Share.”
	Recently Issued Accounting Pronouncements
	In December 2011, the FASB issued new guidance which requires an entity to disclose information about financial instruments and derivative financial instruments that have been offset within the balance sheet, or are subject to a master netting arrangement or similar agreement, regardless of whether they have been offset within the balance sheet. In January 2013, the FASB issued standards to clarify the scope of transactions subject to the disclosure provisions including derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria established under GAAP, or that are subject to a master netting arrangement or similar agreement. Both standards are effective for interim and annual periods beginning on or after January 1, 2013, with required disclosures presented retrospectively for all comparative periods presented. The adoption of this guidance has not had a material impact on our financial statements.
	In February 2013, the FASB issued new guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component; but does not change the current requirements for reporting net income or other comprehensive income in financial statements. The guidance requires presentation of significant amounts reclassified out of accumulated other comprehensive income into earnings by the respective line items of net income, but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The standard is effective prospectively for reporting periods beginning after December 15, 2012 with early adoption permitted. The adoption of this guidance has not had a material impact on our financial statements.
	In February 2013, the FASB issued new guidance that requires measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. Disclosures are required of the nature and amount of the obligations as well as information about such obligations. The guidance is effective for fiscal years beginning after December 15, 2013, and interim periods within those years; and should be applied retrospectively to all prior periods presented. The Partnership does not expect adoption of the new guidance to have a material impact on its financial position or results of operations.

	Note 3—Acquisitions
	Acquisitions
	Gulf Coast Asphalt Company, L.L.C. Acquisition
	In February 2013, the Partnership acquired substantially all of the Mobile, AL and Saraland, AL operating assets related to the terminalling business of GCAC for approximately $85.0 million (“GCAC Purchase Price”) consisting of approximately $25.0 million in cash, $30.0 million in new preferred units (see “Note 8—Preferred Units”) in the Partnership and $30.0 million of assumed debt which was simultaneously extinguished at the acquisition closing by the Partnership.
	The transaction was accounted for as a business combination in accordance with ASC Topic 805, “Business Combinations” (“ASC 805”). The GCAC Purchase Price exceeded the approximately $76.6 million fair value of the identifiable assets acquired and accordingly, the Partnership recognized goodwill of approximately $8.4 million. The Partnership believes the primary items that generated goodwill are both the value of the synergies created between the acquired assets and its existing assets, and its expected ability to grow the business acquired by leveraging its existing customer relationships. Furthermore, the Partnership expects that the entire amount of its recorded goodwill will be deductible for tax purposes. Transaction costs incurred in connection with the acquisition, consisting primarily of legal and other professional fees, totaled approximately $1.9 million and were expensed as incurred in accordance with ASC 805 and included in selling, general and administrative expenses in the consolidated statement of operations.
	GCAC is able to receive up to an additional $5.0 million in cash earnout payments based upon either (i) the throughput activity of one customer over the next three years or (ii) from the closing date through February 8, 2014, any modifications to the acquired contracts whereby the revenue contribution to the Partnership is increased with an offset for any required capital investments made by the Partnership for the contract modifications. As of December 31, 2013, no additional amounts have been paid or are owed to GCAC.

	Motiva Enterprises LLC Acquisition
	In February 2013, the Partnership acquired substantially all of the operating assets related to the Brooklyn, NY terminal (the “Brooklyn Terminal”) of Motiva Enterprises LLC (“Motiva”) for approximately $27.0 million (“Brooklyn Purchase Price”) in cash.
	The transaction was accounted for as a business combination in accordance with ASC 805. The fair value of the identifiable assets acquired of approximately $38.8 million exceeded the Brooklyn Purchase Price. Accordingly, the acquisition has been accounted for as a bargain purchase and, as a result, the Partnership recognized a gain of approximately $11.8 million associated with the acquisition. The gain is included in the line item “Gain on bargain purchase of business” in the condensed consolidated statements of operations. Transaction costs incurred in connection with the acquisition, consisting primarily of legal and other professional fees, totaled approximately $1.5 million and were expensed as incurred in accordance with ASC 805 and included in selling, general and administrative expenses in the condensed consolidated statements of operations.
	The following table summarizes the consideration paid and the amounts of assets acquired at the acquisition date (in thousands):
	Consideration:
	Cash paid to seller	$	27,000

	Inventory		19
	Intangible assets		2,009
	Bargain purchase gain		(11,777	)
	Net assets acquired	$	27,000
	Since the acquisition date in February 2013 through December 31, 2013, the Brooklyn Terminal earned approximately $6.0 million in revenue and $3.5 million of operating income.
	The unaudited pro forma results related to the Motiva acquisition have been excluded as the nature of the revenue-producing activities previously associated with the Brooklyn Terminal have changed substantially post-acquisition from intercompany revenue to third-party generated revenue. In addition, historical financial information for the Brooklyn Terminal prior to the acquisition is not indicative of how the Brooklyn Terminal is being operated since the Partnership’s acquisition and would be of no comparative value in understanding the future operations of the Brooklyn Terminal.
	The above acquisitions were accounted for under the acquisition method of accounting whereby management utilized the services of third-party valuation consultants, along with estimates and assumptions provided by management, to estimate the fair value of the net assets acquired. The third-party valuation consultants utilized several appraisal methodologies including income, market and cost approaches to estimate the fair value of the identifiable assets acquired.

	Gulf LNG Holdings Acquisition
	In connection with the IPO, the Partnership purchased the LNG Interest from an affiliate of GE EFS for approximately $72.7 million. The carrying value of the LNG Interest on the date of acquisition was approximately $64.1 million with a purchase price of approximately $72.7 million and the excess paid over the carrying value of approximately $8.6 million. This excess can be attributed to the underlying long lived assets of Gulf LNG Holdings and is therefore being amortized using the straight line method over the remaining useful lives of the respective asset, which is 28 years.

	Note 7—Debt
	Credit Facility
	On November 12, 2013, concurrent with the closing of the IPO, the Partnership amended and restated the Terminal Credit Facility (the “Credit Facility”) with a syndicate of lenders, under which Arc Terminals Holdings LLC, a wholly owned subsidiary of the Partnership (“Arc Terminals Holdings”) is the borrower. The Credit Facility has an initial term of five years and up to $175.0 million of borrowing capacity (see “Note 2—Summary of Significant Accounting Policies—Other Assets” for discussion regarding deferred financing costs).
	The Credit Facility is available to refinance existing indebtedness, to fund working capital and to finance capital expenditures and other permitted payments and for other lawful corporate purposes and allows the Partnership to request that the maximum amount of the Credit Facility be increased by up to an aggregate of $100.0 million, subject to receiving increased commitments from lenders or commitments from other financial institutions. The Credit Facility is available for revolving loans, including a sublimit of $5.0 million for swing line loans and a sublimit of $10.0 million for letters of credit. The Partnership’s obligations under the Credit Facility are secured by a first priority lien on substantially all of the Partnership’s material assets (other than the LNG Interest). The Partnership and each of the Partnership’s existing subsidiaries (other than the borrower) guarantee and each of the Partnership’s future restricted subsidiaries will also guarantee the Credit Facility. The Credit Facility matures on November 12, 2018.
	Loans under the Credit Facility bear interest at a floating rate based upon the leverage ratio, equal to, at the Partnership’s option, either (a) a base rate plus a range from 100 to 200 basis points per annum or (b) a LIBOR rate, plus a range of 200 to 300 basis points. The base rate is established as the highest of (i) the rate which SunTrust Bank announces, from time to time, as its prime lending rate, (ii) daily one-month LIBOR plus 100 basis points per annum and (iii) the federal funds rate plus 0.50% per annum. The unused portion of the Credit Facility is subject to a commitment fee calculated based upon the Partnership’s leverage ratio ranging from 0.375% to 0.50% per annum. Upon any event of default, the interest rate will, upon the request of the lenders holding a majority of the commitments, be increased by 2.0% on overdue amounts per annum for the period during which the event of default exists.
	The Credit Facility contains certain customary representations and warranties, affirmative covenants, negative covenants and events of default. The negative covenants include restrictions on the Partnership’s ability to incur additional indebtedness, acquire and sell assets, create liens, enter into certain lease agreements, make investments and make distributions. As of December 31, 2013 the Partnership was in compliance with such covenants.
	The Credit Facility requires the Partnership to maintain a leverage ratio of not more than 4.50 to 1.00, which may increase to up to 5.00 to 1.00 during specified periods following a permitted acquisition or issuance of over $200 million of senior notes, and a minimum interest coverage ratio of not less than 2.50 to 1.00. If the Partnership issues over $200.0 million of senior notes, the Partnership will be subject to an additional financial covenant pursuant to which the Partnership’s secured leverage ratio must not be more than 3.50 to 1.00. The Credit Facility places certain restrictions on the issuance of senior notes.
	If an event of default occurs, the agent would be entitled to take various actions, including the acceleration of amounts due under the Credit Facility, termination of the commitments under the Credit Facility and all remedial actions available to a secured creditor. The events of default include customary events for a financing agreement of this type, including, without limitation, payment defaults, material inaccuracies of representations and warranties, defaults in the performance of affirmative or negative covenants (including financial covenants), bankruptcy or related defaults, defaults relating to judgments, nonpayment of other material indebtedness and the occurrence of a change in control. In connection with the Credit Facility, the Partnership and the Partnership’s subsidiaries have entered into certain customary ancillary agreements and arrangements, which, among other things, provide that the indebtedness, obligations and liabilities arising under or in connection with the facility are unconditionally guaranteed by the Partnership and each of the Partnership’s existing subsidiaries (other than the borrower) and each of the Partnership’s future restricted subsidiaries.
	Terminal Credit Facility
	In January 2012, the Partnership entered into a $40.0 million credit facility (the “Terminal Credit Facility”) that had an initial three year term and bore interest based upon the LIBOR plus an applicable margin. The applicable margin was based on the leverage ratio as defined by the Terminal Credit Facility agreement, calculated at the beginning of each interest period. At the time of closing, the Partnership borrowed $22.0 million on the Terminal Credit Facility, applying $20.0 million to extinguish the Partnership’s prior revolving line of credit and the balance was used to pay transaction fees and fund operations. The Terminal Credit Facility agreement required the Partnership to maintain a leverage ratio of not more than 3.75 to 1.00, which decreased to 3.50 to 1.00 on or after March 31, 2013 and a minimum fixed charge ratio of not less than 1.25 to 1.00. At December 31, 2012, the Partnership was in compliance with such covenants. At December 31, 2012, the interest rate was 3.47% and the balance outstanding on the Terminal Credit Facility was $30.5 million.
	In February 2013, the Partnership amended the Terminal Credit Facility to include a $65.0 million term loan and a $65.0 million revolving line of credit. The amended Terminal Credit Facility had an initial three year term and bore interest based upon LIBOR plus an applicable margin. The applicable margin was based on the leverage ratio as defined in the Terminal Credit Facility agreement, calculated at the beginning of each interest period. At the time of the closing, the Partnership borrowed an additional $55.0 million which was used to satisfy the cash portion of the GCAC Purchase Price and to extinguish the debt acquired as a part of the GCAC acquisition. Also in February 2013, the Partnership borrowed an additional $27.0 million to complete the Motiva acquisition. The amended Terminal Credit Facility agreement required the Partnership to maintain an initial leverage ratio of not more than 5.00 to 1.00, which decreased to 4.00 to 1.00 by December 31, 2013 and a minimum fixed charge ratio of not less than 1.25 to 1.00.
	Line of Credit
	In October 2007, the Partnership entered into a revolving line of credit in the amount of $10.0 million. The collateral for the line of credit included the Partnership’s terminal assets. The revolving line of credit had a term of 12 months, with interest calculated monthly at the one month London Interbank Offer Rate (“LIBOR”) plus 2.75%. In addition, there was an interest rate floor of 5.50% and a nonusage fee of 1.0%. The nonusage fee was calculated and payable quarterly and was waived if the average funded balance of any fiscal quarter exceeded a certain threshold. The nonusage fee was included as interest expense in the consolidated financial statements.
	In August 2010, the Partnership amended its existing revolving line of credit to increase the amount available to $20.0 million and extend the maturity to August 1, 2011. In addition, the amendment required the Partnership to maintain a 1:1 ratio of EBITDA to designated expenses, which included mandatory principal payments of indebtedness, interest expense, taxes, distributions in excess of $5.0 million and capital expenditures less capital contributions, gains on the sale of assets and the amount of any new indebtedness.
	In March 2011, the Partnership executed a commitment letter from the lender to extend the term of the revolving line of credit to March 2012 under the same interest rate and nonusage fee terms as previously disclosed.
	This revolving line of credit was extinguished as a part of a new credit facility that the Partnership entered into in January 2012. At the time of extinguishment, the balance outstanding on the revolving line of credit was $20.0 million.

	Note 8—Preferred Units
	In February 2013, the Partnership, as a part of the GCAC Purchase Price (see “Note 3—Acquisitions”), issued 1,500,000 preferred units to GCAC with a value of $30.0 million. The preferred units ranked senior in liquidation preference and distributions to all existing and outstanding common and subordinated units. The preferred units were entitled to 8% annual distributions, paid 45 days following each calendar quarter, assuming the Partnership remained in compliance with all related covenants in the Terminal Credit Facility. If for any reason the Partnership were to be unable to pay the quarterly distributions on time to the preferred unit holders, the distribution amount would have compounded at an 8% annual interest rate until paid. At the time of the IPO the Partnership issued 779 common units and 58,426 subordinated units and made a cash distribution of approximately $29.0 million to GCAC for the contribution of its preferred units in Arc Terminals LP to the Partnership. Prior to the IPO, the Partnership recorded the preferred units as mezzanine equity in accordance with ASC Topic 480 Distinguishing Liabilities from Equity (“ASC 480”) due to the redeemable nature, at the option of the holders, of the preferred units at a fixed and determinable price based upon certain redemption events which were outside the control of the Partnership. During the year ended December 31, 2013, the Partnership paid $1.8 million in cash distributions to the preferred unit holders.

	Initial Public Offering
	On November 6, 2013, Arc Logistics’ common units began trading on the New York Stock Exchange under the symbol “ARCX.” On November 12, 2013, the Partnership closed the IPO by selling 6,000,000 common units representing limited partner interests in us at a price to the public of $19.00 per common unit. On November 18, 2013, the Partnership completed the sale of 786,869 additional common units pursuant to the partial exercise of the underwriters’ over-allotment option at a price to the public of $19.00 per unit.
	In connection with the closing of the IPO and the recapitalization, the following transactions occurred:
		•		Lightfoot contributed all of its limited partner interests in Arc Terminals LP and all of its limited liability company interests in Arc Terminals GP LLC in exchange for 68,617 common units and 5,146,264 subordinated units in the Partnership;
		•		Center Oil contributed all of its limited partner interests in Arc Terminals LP in exchange for 11,685 common units and 876,391 subordinated units in the Partnership;
		•		GCAC contributed its preferred units in Arc Terminals LP in exchange for 779 common units and 58,426 subordinated units in the Partnership and $29.8 million in cash;
		•		Arc Terminals GP LLC and Arc Terminals LP merged with Arc Terminals GP LLC surviving the merger and then changing its name to Arc Logistics LLC;
		•		The public, through the underwriters, contributed $120.2 million of net proceeds in exchange for the issuance of 6,786,869 common units by the Partnership; and
		•		The General Partner maintained its non-economic general partner interest in the Partnership, and was issued 100.0% of the incentive distribution rights of the Partnership.
	As a result of the recapitalization in connection with the IPO, the number of units outstanding was adjusted on a retroactive basis, which is reflected in the table below:
			Preferred Units			Limited Partner			Limited Partner
						Common Units			Subordinated Units

	-1	GCAC contributed its preferred units in Arc Terminals LP in exchange for 779 common units and 58,426 subordinated units in the Partnership and $29.8 million in cash.
	Cash Distribution Policy
	The partnership agreement provides that the General Partner will make a determination no less frequently than every quarter as to whether to make a distribution, but the partnership agreement does not require the Partnership to pay distributions at any time or in any amount. Instead, the board of directors of the General Partner has adopted a cash distribution policy that sets forth the General Partner’s intention with respect to the distributions to be made to unitholders. Pursuant to the cash distribution policy, within 60 days after the end of each quarter, the Partnership expects to distribute to the holders of common and subordinated units on a quarterly basis at least the minimum quarterly distribution of $0.3875 per unit, or $1.55 per unit on an annualized basis, to the extent the Partnership has sufficient cash after establishment of cash reserves and payment of fees and expenses, including payments to the General Partner and its affiliates.
	The board of directors of the General Partner may change the foregoing distribution policy at any time and from time to time, and even if the cash distribution policy is not modified or revoked, the amount of distributions paid under the policy and the decision to make any distribution is determined by the General Partner. As a result, there is no guarantee that the Partnership will pay the minimum quarterly distribution, or any distribution, on the units in any quarter. However, the partnership agreement contains provisions intended to motivate the General Partner to make steady, increasing and sustainable distributions over time.
	The partnership agreement generally provides that the Partnership will distribute cash each quarter in the following manner:
		•		first, to the holders of common units, until each common unit has received the minimum quarterly distribution of $0.3875 plus any arrearages from prior quarters;
		•		second, to the holders of subordinated units, until each subordinated unit has received the minimum quarterly distribution of $0.3875; and
		•		third, to all unitholders pro rata, until each has received a distribution of $0.4456.
	If cash distributions to the Partnership’s unitholders exceed $0.4456 per unit in any quarter, the Partnership’s unitholders and the General Partner, as the initial holder of the incentive distribution rights, will receive distributions according to the following percentage allocations:
			Marginal Percentage
			Interest
			in Distributions
	Total Quarterly Distribution Per Unit Target Amount		Unitholders			General
						Partner
	above $0.3875 up to $0.4456			100	%		0	%
	above $0.4456 up to $0.4844			85	%		15	%
	above $0.4844 up to $0.5813			75	%		25	%
	above $0.5813			50	%		50	%
	The Partnership refers to additional increasing distributions to the General Partner as “incentive distributions.”
	The principal difference between the Partnership’s common units and subordinated units is that in any quarter during the subordination period, holders of the subordinated units are not entitled to receive any distributions from operating surplus until the common units have received the minimum quarterly distribution for such quarter plus any arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated units will not accrue arrearages.
	The subordination period will end on the first business day after the Partnership has earned and paid at least (1) $1.55 (the minimum quarterly distribution on an annualized basis) on each outstanding common unit and subordinated unit for each of three consecutive, non-overlapping four quarter periods ending on or after September 30, 2016 or (2) $2.325 (150.0% of the annualized minimum quarterly distribution) on each outstanding common unit and subordinated unit and the related distribution on the incentive distribution rights for a four-quarter period ending immediately preceding such date, in each case provided there are no arrearages on the Partnership’s common units at that time.
	The subordination period will also end upon the removal of the General Partner other than for cause if no subordinated units or common units held by holder(s) of subordinated units or their affiliates are voted in favor of that removal. When the subordination period ends, all subordinated units will convert into common units on a one-for-one basis, and all common units thereafter will no longer be entitled to arrearages.

Earnings Per Unit ("EPU")	'
	Note 10—Earnings Per Unit (“EPU”)
	The Partnership uses the two-class method when calculating the net income per unit applicable to limited partners. The two-class method is based on the weighted-average number of common and subordinated units outstanding during the period. Basic net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting distributions, if any, by the weighted-average number of outstanding common and subordinated units. Payments made to the Partnership’s unitholders are determined in relation to actual distributions paid and are not based on the net income allocations used in the calculation of net income per unit.
	Diluted net income per unit applicable to limited partners includes the effects of potentially dilutive units on the Partnership’s units. For the year ended December 31, 2013 the only potentially dilutive units outstanding consisted of the preferred units settled as part of the IPO (see “Note 8—Preferred Units”).
	As a result of the recapitalization in connection with the IPO, earnings per unit was adjusted on a retroactive basis.

	Payments to the General Partner and its affiliates
	The General Partner conducts, directs and manages all activities of the Partnership. The General Partner is reimbursed on a monthly basis, or such other basis as may be determined, for: (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership and its subsidiaries; and (ii) all other expenses allocable to the Partnership and its subsidiaries or otherwise incurred by the General Partner in connection with operating the Partnership and its subsidiaries’ businesses (including expenses allocated to the General Partner by its affiliates).
	For the years ended December 31, 2013, 2012 and 2011 the General Partner incurred expenses of $2.5 million, $2.6 million and $2.6 million, respectively. Such expenses are reimbursable from the Partnership and are reflected in the selling, general and administrative—affiliate line on the consolidated statements of operations. As of December 31, 2013 and December 31, 2012, the Partnership had a payable of approximately $0.1 million and $0.2 million, respectively, to the General Partner which is reflected as due to general partner in the accompanying consolidated balance sheets.
	Registration Rights Agreement
	In connection with the IPO, the Partnership entered into a registration rights agreement with the Sponsor. Pursuant to the registration rights agreement, the Partnership is required to file a registration statement to register the common units issued to the Sponsor and the common units issuable upon the conversion of the subordinated units upon request of the Sponsor. In addition, the registration rights agreement gives the Sponsor piggyback registration rights under certain circumstances. The registration rights agreement also includes provisions dealing with holdback agreements, indemnification and contribution and allocation of expenses. These registration rights are transferable to affiliates and, in certain circumstances, to third parties.
	Assignment and Equity Purchase Agreement with GE EFS
	In connection with the IPO, the Partnership entered into an assignment and equity purchase agreement with an affiliate of GE EFS that enabled the Partnership to acquire a 10.3% interest in Gulf LNG Holdings. Approximately $72.7 million of the proceeds from the IPO were used to acquire the LNG Interest on the closing date of the IPO.
	Other Transactions with Related Persons
	GCAC guarantees up to $20 million of the Partnership’s Credit Facility. Under certain circumstances, the lenders may release GCAC from such guarantee.
	Storage and Throughput Agreements with Center Oil
	During 2007, the Partnership acquired seven terminals from Center Oil for $35.0 million in cash and 750,000 subordinated units in the Partnership. In connection with this purchase, the Partnership entered into a storage and throughput agreement with Center Oil whereby the Partnership provides storage and throughput services for various petroleum products to Center Oil at the terminals acquired by the Partnership in return for a fixed per barrel fee for each outbound barrel of Center Oil product shipped or committed to be shipped. The throughput fee is calculated and due monthly based on the terms and conditions as set forth in the storage and throughput agreement. In addition to the monthly throughput fee, Center Oil agrees to pay the Partnership a fixed per barrel fee for any additives added into Center Oil’s product.
	The term of the storage and throughput agreement extends through June 2017. The agreement can be terminated by either party upon written notification of such party’s intent to terminate this agreement at the expiration of such applicable term and must be received by the other party not later than eighteen months prior to the expiration of the applicable term. If notice is not provided by Center Oil, the agreement automatically renews for three additional three-year terms at rates adjusted for inflation as determined in accordance with the terms of the agreement.
	In February 2010, the Partnership acquired a 50% undivided interest in the Baltimore, MD terminal. In connection with the acquisition, the Partnership acquired an existing agreement with Center Oil whereby the Partnership provides ethanol storage and throughput services to Center Oil. The Partnership charges Center Oil a fixed fee for storage and a fee based upon ethanol throughput at the Baltimore, MD terminal. The storage and throughput fees are calculated monthly based on the terms and conditions of the storage and throughput agreement. The agreement has a one-year term and comes up for renewal in May 2015.
	In May 2011, the Partnership entered into an agreement to provide refined products storage and throughput services to Center Oil at the Baltimore, MD terminal. The Partnership charges Center Oil a fixed fee for storage and a fee for ethanol blending and any additives added to Center Oil’s product. The storage and throughput fees are calculated monthly based on the terms and conditions of the storage and throughput agreement. The agreement has a one-year term and comes up for renewal in May 2015.
	In May 2013, the Partnership entered into an agreement to provide gasoline storage and throughput services to Center Oil at the Brooklyn, NY terminal. The Partnership charged Center Oil a fixed per bbl fee for each inbound delivery of ethanol and every outbound barrel of product shipped or committed to be shipped and a fee for any ethanol blending and additives added to Center Oil’s product. The storage and throughput fees are calculated monthly based on the terms and conditions of the storage and throughput agreement. The agreement has a one-year term with evergreen renewal provisions.
	Storage and Throughput Agreements with GCAC
	During 2013, the Partnership acquired terminal assets from GCAC for $25.0 million in cash, $30.0 million of preferred units in the Partnership and the assumption of approximately $30.0 million in debt. In connection with this purchase, the Partnership entered into a storage and throughput agreement (the “GCAC Agreement 1”) with GCAC whereby the Partnership will provide storage and throughput services for various petroleum products to GCAC at the existing terminals acquired by the Partnership in return for a fixed per barrel storage fee plus a fixed per barrel fee for related throughput and other ancillary services. In addition, the Partnership entered into a second storage and throughput agreement with GCAC (the “GCAC Agreement 2”) whereby the Partnership will build an additional 150,000 barrels of storage tanks for GCAC to store and throughput various petroleum products in return for similar economic terms of GCAC Agreement 1.
	The initial term of GCAC Agreements 1 and 2 is approximately five years. These agreements can be mutually extended by both parties as long as the extension is agreed to 180 days prior to the end of the initial termination date, otherwise the Partnership has the right to lease the storage capacity to any third party.
	The total revenues associated with the storage and throughput agreements for Center Oil and GCAC and reflected in the Revenues—Related parties line on the consolidated statements of operations are as follows:
		For the Year Ended December 31,

Organization	'
	Organization
	The Partnership is a fee-based, growth-oriented Delaware limited partnership formed by Lightfoot in 2007 to own, operate, develop and acquire a diversified portfolio of complementary energy logistics assets. The Partnership is principally engaged in the terminalling, storage, throughput and transloading of crude oil and petroleum products. The Partnership is focused on growing its business through the optimization, organic development and acquisition of terminalling, storage, rail, pipeline and other energy logistics assets that generate stable cash flows.
	Unless the context clearly indicates otherwise, references in these consolidated financial statements to “Arc Terminals,” or the “Partnership” when used for periods prior to November 12, 2013, the closing of the initial public offering of Arc Logistics Partners LP (the “IPO”), refer to Arc Terminals LP and its subsidiaries, which were contributed to Arc Logistics Partners LP in connection with the IPO, and references to “Arc Logistics,” or the “Partnership” when used for periods on or after the closing of the IPO refer to Arc Logistics Partners LP and its subsidiaries. Unless the context clearly indicates otherwise, references to our “General Partner” for periods prior to the closing of the IPO refer to Arc Terminals GP LLC which owned the general partner interest in Arc Terminals and references to our “General Partner” for periods on or after the closing of the IPO refer to Arc Logistics GP LLC, the General Partner of Arc Logistics. References to our “Sponsor” or “Lightfoot” refer to Lightfoot Capital Partners, LP and its general partner, Lightfoot Capital Partners GP LLC. References to “GCAC” refer to Gulf Coast Asphalt Company, L.L.C., which contributed its preferred units in Arc Terminals to the Partnership upon the consummation of the IPO. References to “Center Oil” refer to GP&W, Inc., d.b.a. Center Oil, and affiliates, including Center Terminal Company-Cleveland, which contributed its limited partner interests in Arc Terminals to the Partnership upon the consummation of the IPO. References to “Gulf LNG Holdings” refer to Gulf LNG Holdings Group, LLC and its subsidiaries, which own a liquefied natural gas regasification and storage facility in Pascagoula, MS, which is referred to herein as the “LNG Facility.” The Partnership used a portion of the proceeds from the IPO to acquire a 10.3% limited liability company interest in Gulf LNG Holdings, which is referred to herein as the “LNG Interest.”
Basis of Presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and under the rules and regulations of the Securities and Exchange Commission (“SEC”). The accompanying consolidated financial statements include the accounts of the Partnership and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	The Partnership has disclosed consolidated figures of the Partnership as if the Partnership had operated since the inception of Arc Terminals. The contribution of Arc Terminals to Arc Logistics in connection with the IPO was not considered a business combination accounted for under the purchase method as it was a transfer of assets under common control and, accordingly, balances have been transferred at their historical cost. The combined financial statements for the periods prior to the contribution on November 12, 2013 have been prepared using Arc Terminals’ historical basis in the assets and liabilities, and include all revenues, costs, assets and liabilities attributed to Arc Terminals.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The most significant estimates relate to the valuation of acquired businesses, goodwill and intangible assets and the useful lives of intangible assets and property, plant and equipment. Actual results could differ from those estimates.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Partnership includes demand deposits with banks and all highly liquid investments with original maturities of three months or less in cash and cash equivalents. These balances are valued at cost, which approximates fair value.
Trade Accounts Receivable	'
	Trade Accounts Receivable
	Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Partnership reserves for specific trade accounts receivable when it is probable that all or a part of an outstanding balance will not be collected. The Partnership regularly reviews collectability and establishes or adjusts the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. There were no reserves for uncollectible amounts as of December 31, 2013 and 2012. During the year ended December 31, 2013, the Partnership wrote off less than $0.1 million of uncollectible receivables. No other amounts have been deemed uncollectible in the periods presented in the consolidated statements of operations.
Inventories	'
	Inventories
	Inventories consist of additives which are sold to customers and mixed with the various customer-owned liquid products stored in the Partnership’s terminals. Inventories are stated at the lower of cost or estimated net realizable value. Inventory costs are determined using the first-in, first-out method.
Other Current Assets	'
	Other Current Assets
	Other current assets consist primarily of prepaid expenses and deposits.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment is recorded at cost, less accumulated depreciation. The Partnership owns a 50% undivided interest in the property, plant and equipment at two terminal locations. At the time of acquisition, these assets were recorded at 50% of the aggregate fair value of the related property, plant and equipment. Expenditures for routine maintenance and repairs are charged to expense as incurred. Major improvements or expenditures that extend the useful life or productive capacity of assets are capitalized. Depreciation is recorded over the estimated useful lives of the applicable assets, using the straight-line method. The estimated useful lives are as follows:
	Building and site improvements		5 - 40 years
	Tanks and trim		2 - 40 years
	Machinery and equipment		2 - 25 years
	Office furniture and equipment		3 - 10 years
	Capitalized costs incurred by the Partnership during the year for major improvements and capital projects that are not completed as of year-end are recorded as construction in progress. Construction in progress is not depreciated until the related assets or improvements are ready for intended use. Additionally, the Partnership capitalizes interest costs as a part of the historical cost of constructing certain assets and includes such interest in the property, plant and equipment line on the balance sheet. Capitalized interest for the years ended December 31, 2013 and 2012 was $0.4 million and $0.1 million, respectively
Intangible Assets	'
	Intangible Assets
	Intangible assets primarily consist of customer relationships, acquired contracts and a covenant not to compete which are amortized on a straight-line basis over the expected life of each intangible asset.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the estimated fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated.
	During the year ended December 31, 2013, events and circumstances indicated that approximately $4.7 million of assets of one of the Partnership’s terminals might be impaired. However, the Partnership’s estimate of undiscounted cash flows indicated that such carrying amounts were expected to be recovered. Nonetheless it is possible that the estimate of undiscounted cash flows may change in the near term resulting in the need to write down the carrying value of those assets.
	No impairment charges were recorded through December 31, 2013 and 2012.
Goodwill	'
	Goodwill
	Goodwill represents the excess of consideration paid over the fair value of net assets acquired in a business combination. Goodwill is not amortized but instead is assessed for impairment at least annually or when facts and circumstances warrant. Goodwill impairment is determined using a two-step process. The first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. The Partnership determines the fair value of its single reporting unit by blending two valuation approaches: the income approach and a market value approach. The Partnership determined at December 31, 2013, there were no impairment charges and no event indicating an impairment has occurred.
	No impairments were recorded against goodwill through December 31, 2013 and 2012.

Other Assets	'
	Other Assets
	Other assets consist primarily of debt issuance costs related to the Credit Facility amendment entered into in November 2013 (see “Note 7—Debt”). Debt issuance costs are capitalized and amortized over the term of the related debt using straight line amortization, which approximates the effective interest rate method. As of December 31, 2013, these costs were approximately $1.7 million. Fluctuations during the year ended December 31, 2013 included write offs of approximately $3.5 million, representing the unamortized debt issuance cost prior to the refinancing of the debt and approximately $2.9 million in deferred costs associated with the IPO that were offset against the proceeds of the IPO.
Investment in Unconsolidated Affiliate	'
	Investment in Unconsolidated Affiliate
	In connection with the IPO, the Partnership purchased the LNG Interest from an affiliate of GE EFS for approximately $72.7 million. The Partnership accounts for the LNG Interest using the equity method of accounting.
Revenue Recognition	'
	Revenue Recognition
	Revenues from leased tank storage and delivery services are recognized as the services are performed. Revenues also include the sale of excess products and additives which are mixed with customer-owned liquid products. Revenues for the sale of excess products and additives are recognized when title and risk of loss passes to the customer.
Income Taxes	'
	Income Taxes
	Taxable income or loss of the Partnership generally is required to be reported on the income tax returns of the limited partners in accordance with the terms of the partnership agreement. Accordingly, no provision has been made in the accompanying consolidated financial statements for the limited partners’ federal income taxes. There are certain entity level state income taxes that are incurred at the Partnership level and have been recorded during the years ended December 31, 2013, 2012 and 2011.
	Tax returns for the years ended December 31, 2013, 2012, 2011, 2010 and 2009 are open to IRS and state audits. The Partnership is not aware of any uncertain tax positions as of December 31, 2013 and 2012.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Fair value measurements are derived using inputs and assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. GAAP establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This three-tier hierarchy classifies fair value amounts recognized or disclosed in the financial statements based on the observability of inputs used to estimate such fair values. The classification within the hierarchy of a financial asset or liability is determined based on the lowest level input that is significant to the fair value measurement. The hierarchy considers fair value amounts based on observable inputs (Level 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). At each balance sheet reporting date, the Partnership categorizes its financial assets and liabilities using this hierarchy.
	The amounts reported in the balance sheet for cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value because of the short-term maturities of these instruments (Level 1). The carrying amount of the Terminal Credit Facility as well as the Partnership’s Credit Facility approximated fair value due to its short-term nature and market rate of interest (Level 2).
	The Partnership believes that its valuation methods are appropriate and consistent with the values that would be determined by other market participants. However, the use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.
Limited Partners' Net Income Per Unit	'
	Limited Partners’ Net Income Per Unit
	The Partnership uses the two-class method in the computation of earnings per unit since there is more than one participating class of securities. Basic earnings per common and subordinated unit are determined by dividing net income allocated to the common units and subordinated units, respectively, after deducting the amount allocated to the preferred unitholders, by the weighted average number of outstanding common and subordinated units, respectively, during the period. The overall computation, presentation and disclosure of the Partnership’s limited partners’ net income per unit are made in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260 “Earnings per Share.”
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	In December 2011, the FASB issued new guidance which requires an entity to disclose information about financial instruments and derivative financial instruments that have been offset within the balance sheet, or are subject to a master netting arrangement or similar agreement, regardless of whether they have been offset within the balance sheet. In January 2013, the FASB issued standards to clarify the scope of transactions subject to the disclosure provisions including derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria established under GAAP, or that are subject to a master netting arrangement or similar agreement. Both standards are effective for interim and annual periods beginning on or after January 1, 2013, with required disclosures presented retrospectively for all comparative periods presented. The adoption of this guidance has not had a material impact on our financial statements.
	In February 2013, the FASB issued new guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component; but does not change the current requirements for reporting net income or other comprehensive income in financial statements. The guidance requires presentation of significant amounts reclassified out of accumulated other comprehensive income into earnings by the respective line items of net income, but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The standard is effective prospectively for reporting periods beginning after December 15, 2012 with early adoption permitted. The adoption of this guidance has not had a material impact on our financial statements.
	In February 2013, the FASB issued new guidance that requires measurement of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. Disclosures are required of the nature and amount of the obligations as well as information about such obligations. The guidance is effective for fiscal years beginning after December 15, 2013, and interim periods within those years; and should be applied retrospectively to all prior periods presented. The Partnership does not expect adoption of the new guidance to have a material impact on its financial position or results of operations.
